hey, this is Rami ... I lead HW team at Cloudflare. Great Q! .. in our case, there was a sweet spot between the number of cores, the L3 cache per core, NUMA latencies, mem bw per core, cost & power. The 48c gave us the best req per second per $, and it likely was due to a combination of all these things.

We have two more blogs that will come out probably today, which will shed more light on why AMD worked better for us.

Hi, this is Drew from Netflix.. Just curious, are you running single socket rome in numa or non-numa mode? I've seen better performance in NPS=4 mode myself. We seem to see about a 7% increase when moving from NPS=1 to NPS=2 and another 7% going to NPS=4.

Yes, we got the most perf when we used NPS=4.

Stay tuned for 3 more blogs this week ... they will give deeper analysis on the perf % gains we saw and why.
